10-100 Duplicate Elimination : How To Use A Dim Numbers() As Integer
Oct 5, 2011
how to use a Dim numbers() As Integer thats bout it here is my problem that iam facing :Use a one-dimensional array to solve the following problem: Read in 20 numbers, each of which is between 10 and 100, inclusive. As Each number is read, print it only if it is not a duplicate of a number already read. provide the "worst case" (in which all 20 numbers are different). use the smallest possible array to solve this problem.
I looked for code snippets online to do this project, have not really found any elegant code snippets except for this one.My project is to use a one-dimensional array to solve following:Read in 20 numbers, each of which is between 10 and 100 inclusive.As each number is read, display it in NumbersEnteredListBox and if it's not a duplicate of a number already read, diplay it in UniiqueValuesListBox. Provide "worst case" all 20 numbers are different.[code].....
I want to understand what I'm learning so it will stick. What is Ubound? I realize I need to rewrite some of this to fit to what I'm trying to accomplish, but I want to understand it first. This is not in the book thus far. The codes I have found were sorry...horrible...I want to learn to write better with less words if possible?
The program must generate 6 unique random numbers but when I click display numbers sometimes it gives me 6 unique numbers and sometimes I get duplicate numbers. I will add the code I have so far.
Public Class frmMain
Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
I have a code that generates random code using a set of letters. One for a random pin and another for a random code. I can loop the generation of my codes depending on the input. When I try to generate 1 to 3 set of codes it works fine. but if it's 4 and above. I always get a duplicate set of random numbers. I don't what wrong. My code for generating my codes are in vb.net and be passed to a stored procedure for inventory.
Button event: Protected Sub genCodeBtn_Click(sender As Object, e As EventArgs) Handles genCodeBtn.Click connection = accDB.databaseConnect()
So basically I'm making a BINGO game on vb 2008 and i have a "call number" button. The letter and numbers get added to a list box each time. But i do not want the same number to be called. Is there a way that the program can read the items in the list box and not generate (Randomly) the same value again to be displayed in the label.This is what i have:
I am having trouble in finding duplicate numbers in an array.the first one is to create an array with duplicates and then display the number that has been duplicated and how many times it has been duplicated.
label10 displays which is the highest number label12 displays which is the lowest number label14 displays which is the number that is duplicated
My codes don't run 100% correct.:'( Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Label6.Text = Val(TextBox1.Text) Label7.Text = Val(TextBox2.Text) Label8.Text = Val(TextBox3.Text) [Code] .....
I have been working on a pythagorean theorem calculator and am actually stuck on the final bit of code. What I am trying to do is check the values (integers) inside a listbox, remove duplicate number (both values), and input one of the values into a textbox.
Here is an example of what I am doing:
LISTBOX VALUES 2 2 3
[code]....
When the program runs, check listbox value #1 and listbox value #2, if listbox value #1 and #2 match (2 & 2), input that value (not both duplicates) into a variable, remove both of the duplicate values, continue checking the rest of the values, and finally multiply the leftover values. I am sure that sounds confusing. Here is what the final output will look like
how to eliminate duplicate random numbers displayed in labels ( a column of 5 labels). This is for a BINGO game i am doing. I have tried a Do .. Loop until structure with a for next but i am not sure how to proceed:
Do For NumB = 0 To 4 B(NumB) = Int(15 * Rnd() + 1) itemarrayB(NumB).Text = B(NumB) Next Loop Until
i have wrote a loop to search for duplicate numbers within a column in a database which i have got fine but when i find a duplicate i would like to get the all of the row so if 33 was a duplicate i would like to get the following row.
33MarkWhitesideM12/07/1958Michaeluuu
I have tried to do this buy use something i saw on msnd's website:
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")
However if i change the line to notice the i beside the like
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")
but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.
Private Sub checkRowsForDups() Dim customerDS As DataSet Dim dupArray As New ArrayList
I have this project that let user inputs 5 different numbers from 1 to 50. But I want to validate it before saving to DB that i will be 5 unique numbers.
I am making a Bingo game. I have a button which keeps on calling numbers which are then added to a list box. How do i make it that the numbers called don't repeat (get displayed in the "number called" label). Is there a way to use items already added in the list box to eliminate duplicate numbers.
I've used a numericupdown to select a number and then save it to a .dat file When i try to display the integer in a listbox, it appears as a random sequence of numbers.
for example, if i input 200 into the numbericupdown, when displayed in the listbox, it is shown as 538976366
Is it an error with the properties with either the numericupdown or the listbox? or do you need to see my code?
let me know if you need any more information or code
I need to document binary files containing integer and real numbers. I use BinaryReader, and BinaryWriter classes, with functions like ReadInt16, ReadSingle, or ReadByte. The files should be readable by any other hardware architecture/OS besides x86/Windows.
I need to document the type of default binary encoding, and can't find the MS documentation.The best I found says that it uses UTF8, but as I understand, UTF8 is for text formats, not for binary numbers.
I suposse that the answer I are looking for, is something like "little endian" or "big endian" format.
Iam trying to write code that read integer numbers from user (intered in form) and put it in array and then i will do some calcuation.I declare The array z and index of array p at begining of the class (global), I dont specify the size of arry couz that it depend on user.
If CInt(l1.Text) >= 0 Then z(p) = CInt(l1.Text.ToUpper) l1.Clear() l1.Focus()
I have this data in txt file and the data keeps changing all the time.

I would like to read all lines and compare, if the same name and same address is found, which is in the [......], then i need to count it and show the most frequent buyer!should i read it all and put in array, and compare and put the duplicate data and count into another array?
I have a List object and I want to remove the duplicated items but leaving at least one of the duplicated items in the list;I wrote something like this however I would optimize this code for better performance, is there something faster?
Const chars As String = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" Dim rnd As New Random() Dim mylist As List(Of String) = Enumerable.Range(1, 100).Select(Function(i)
ive got some simple problem i cant understand how to solve.
str(1) is an array and integer(or double, tried both) a(1) is an array and integer (or double, tried both) a(1) = a(1) + 1 Label1.Text = str(1) + a
the big part is where i get: operator '+' is not defined for types 'integer' and '1-dimensional array of integer'.why do i get that message and what does it mean? how do i make the code do what i want?
I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing item = item.NextItem Loop
I am a newbie in VB and I got a piece of code which can display the current running program. I need to use that in VB2005 and I got the below error message. Can anyone help how to fix it?[code]
I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer Dim arginitP As Integer
[Code]...
Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer
I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.
Sub GetStatistics(ByVal ProductNumbers As List(Of String), ByRef Passed As Integer, ByRef FailedProducts As List(Of String)) Passed = 0 FailedProducts = Nothing
this is for a BINGO game final project that I already turned in but this just bugged me that I could not get the sorting figured out. I am trying to get this to sort the random numbers in to columns under the correct letters but I keep getting the error Operator '>=' is not defined for types '1-dimensional array of Integer' and 'Integer' under the line:
I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists Where (f.UserID = Profile.ID) Select f.FriendID).Except(From g In myEntities.GuestLists Where g.EventID = _id Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?
Why doesn't CDate(integer) work where integer has format of YYYYMMDD ?and why won't this stupid site let me submit such a short question when I have nothing else to add except some waffle at the end
